Which sugar is most commonly used in households?

Sucrose is the sugar most commonly used in households primarily due to its widespread availability and versatility in cooking and baking. It is a disaccharide composed of glucose and fructose, making it sweeter than other sugars and ideal for use in various recipes, from desserts to beverages. Its granular form, stability, and ability to enhance flavor make sucrose a popular choice for sweetening foods and drinks.

In many parts of the world, sucrose is derived from sugar cane or sugar beet, contributing to its abundance in grocery stores and kitchens. It is also the sugar typically encountered in table settings and is often referred to simply as "sugar." While other sugars like glucose, fructose, and lactose have their specific uses — such as in energy foods or dairy products — none match the commonality and broad application of sucrose in everyday cooking and consumption.
